I actually started to look into this when I saw her video. I know we've talked about this before, but I never really began to understand them myself. So yes, it sparked my curiosity....

No, they don't "worship" Satan. They don't worship anything. Satan is a symbol to them of what it means to be on a quest for knowledge.

They are basically an activist group that uses the veil of religion to fight for religious freedom. I watched another video about the recently established Seattle Chapter. Honestly the work they do is very much the same kind of work that other Atheist groups do. They petition and legislate to make a point and to protect people from the abuses of religion.

Also, the word satan is apparently derived from the word opposer, or opposition. When La'Veyan Satanists use the word, it is with that meaning in mind. I haven't read the article but I assume it's talking about La'Veyan Satanism.

Surprisingly, most card-carrying satanists do not worship Satan or any other form of the devil -- they are actually atheists.

So I read that and I got curious, because I never heard of that before. So I decided to dive into it further more.

As Anton LaVey explained in his classic work The Satanic Bible, Man—using his brain—invented all the Gods, doing so because many of our species cannot accept or control their personal egos, feeling compelled to conjure up one or a multiplicity of characters who can act without hindrance or guilt upon whims and desires.

Since the Satanist understands that all Gods are fiction, instead of bending a knee in worship to—or seeking friendship or unity with—such mythical entities, he places himself at the center of his own subjective universe as his own highest value. We Satanists are thus our own “Gods,” and as beneficent “deities”

So "Atheistic" Satanism believes that each individual is his/her own god? You don't believe in an external god however you believe yourself to be a god. That does not quite sound like "atheistic" logic at all.

Lately in my experience with differing non-Abrahamic faith religions, I tend to see that some like to conveniently say that they practice the "atheistic" version of their religion. I guess its the flavor of the month to call yourself an "Atheist" nowadays.
